==Overview==
 
 
'''Paresthesia''' or '''paraesthesia''' (in [[British English]]) is a [[sensation]] of [[Wiktionary:tingling|tingling]], [[Wiktionary:pricking|pricking]], or '''[[Wiktionary:numbness|numbness]]''' of a [[person]]'s [[skin]] with no apparent long-term physical effect, more generally known as the feeling of '''pins and needles''' or of a [[human limb|limb]] being "asleep" (but not directly related to the phenomenon of [[sleep]]). Its manifestation may be transient or chronic.
 
 
==Chronic condition==
 
Chronic paresthesia indicates a problem with the functioning of [[neuron]]s. This malfunction, which is especially common in older individuals, is often the result of poor [[Circulation (physiology)|circulation]] in the limbs (such as in peripheral vascular disease), which may be caused by [[atherosclerosis]] — the build up of [[plaque]] on [[artery]] walls. Without a proper supply of [[blood]] and [[nutrients]], nerve cells can no longer adequately send signals to the [[brain]]. Because of this, paresthesia can also be a symptom of [[vitamin]] deficiency and [[malnutrition]], as well as [[metabolism|metabolic]] disorders like [[Diabetes mellitus|diabetes]], [[hypothyroidism]], and [[hypoparathyroidism]].
 
 
Irritation to the nerve can also come from [[inflammation]] to the surrounding tissue. Joint conditions such as [[rheumatoid arthritis]] and [[carpal tunnel syndrome]] are common sources of paresthesia.
 
 
Another cause of paresthesia, however, may be direct damage to the nerves themselves, or [[neuropathy]], which can stem from [[injury]] or [[infection]] such as [[Lyme disease]], or which may be indicative of a current [[neurological disorder]]. Chronic paresthesia can sometimes be symptomatic of serious conditions, such as a [[transient ischemic attack]], a [[brain tumor]], [[motor neurone disease]], or [[autoimmune disorder]]s like [[multiple sclerosis]] or [[lupus erythematosus]]. A diagnostic evaluation by a [[medical doctor|doctor]] is necessary to rule these out.
 
  
Paresthesiae of the [[mouth]], hands, and feet are common, transient symptoms of the related conditions of [[hyperventilation syndrome]] and [[panic attack]]s.

==Treatment==

== [[Paraesthesia natural history, complications and prognosis|Natural History, Complications and Prognosis]] ==
  
Treatment should be decided by a [[neurologist]].  Medications offered can include [[prednisone]], intravenous [[gamma globulin]] (IVIG) and [[anticonvulsants]] such as [[gabapentin]] or [[gabitril]], amongst others.
+
== Diagnosis ==
  
In some cases, rocking the head from side to side will painlessly remove the "pins and needles" sensation in less than a minute. A tingly hand or arm is often the result of compression in the bundle of nerves in the neck. Loosening the neck muscles releases the pressure. Compressed nerves lower in the body govern the feet, and standing up and walking around will typically relieve the sensation. <ref>http://health.msn.com/menshealth/articlepage.aspx?cp-documentid=100119940&GT1=7538</ref>

An arm that has "fallen asleep" may also be "awoken" more quickly by clenching and unclenching the fist several times; the muscle movement increases blood flow and helps the limb return to normal.
